General Safety
1. General Safety Instructions
General and Servicing Safety Instructions
Read and observe all Warning and Caution hazard alert
messages. The alerts provide information that can help prevent
serious personal injury, damage to components, or both.
Failure to follow the instructions and safety
precautions in this manual could result in
improper servicing or operation leading to
component failure which, if not avoided,
could result in death or serious injury.
All maintenance should be performed by a properly trained
technician using proper/special tools, and safe procedures.
NOTE:
In the United States, workshop safety requirements
are defined by federal and/or state Occupational
Safety and Health Act (OSHA). Equivalent laws may
exist in other countries. This manual is written based
on the assumption that OSHA or other applicable
employee safety regulations are followed by the
location where work is performed.
Properly support and secure the vehicle from unexpected
movement when servicing the unit.
Failure to properly support and secure the
vehicle and axles prior to commencing work
could create a crush hazard which, if not
avoided, could result in death or serious injury.
Several maintenance procedures in this manual require re-positioning
of the brake chamber, brake calipers and/or ABS system. Consult
the manufacturer’s manual for procedures on the proper
operation of brake chamber, brake calipers and/or ABS system.
Service both roadside and curbside of an axle. Worn parts
should be replaced in sets. Key components on each axle’s
braking system, such as friction material and rotors will
normally wear over time.
IMPORTANT:
Key components on each axle’s braking
system, including brake pads and brake
rotors, are intended to wear over time. Worn
parts should be replaced in sets on both
the driver and curb side of an axle.
Failure to follow manufacturer’s instructions
regarding spring pressure or air pressure
control could allow uncontrolled release
of energy which, if not avoided, could
result in death or serious injury.
The wheel contact surfaces between the wheel and hub
MUST NOT receive additional paint.
IMPORTANT:
The wheel contact surfaces MUST be clean,
smooth and free from grease.
Failure to keep wheel and hub contact surfaces
clean and clear of foreign material could
allow wheel/hub separations which, if not
avoided, could result in death or serious injury.
Only the wheel and tire sizes approved by the trailer builder
can be used.
Operational and Road Safety Instructions
Before operating vehicle, ensure that the maximum permissible
axle load is not exceeded and that the load is distributed
equally and uniformly.
Make sure that the brakes are not overheated from
continuous operation.
Failure to minimize the use of brakes during
overheating conditions could result in
deterioration of brake efficiency which
could result in death or serious injury.
The parking brake MUST NOT be immediately applied
when the brakes are overheated. Refer to the rotor wear
inspection information in Section 6.2.
If the parking brake is immediately
applied to the brakes when overheated,
the brake discs could be damaged by
different stress fields during cooling.
Observe the operating recommendation of the trailer
manufacturer for off-road operation of the installed axles.
IMPORTANT:
The definition of OFF-ROAD means driving
on non-asphalt/non-concrete routes, e.g.
gravel roads, agricultural and forestry tracks,
on construction sites and in gravel pits.
IMPORTANT:
Off-road operation of axles beyond
the approved application design could
result in damage and impair suspension
system performance.
SAF
®
axles require routine service, inspection and
maintenance in order to maintain optimum performance,
and operational safety as well as an opportunity to
recognize natural wear and defects before they become
serious. Refer to the Routine Service Schedule in Section 19.
Failure to inspect and maintain the SAF-
HOLLAND
®
P89 disc brake axle as outlined
in Section 19 can result in brake or wheel
bearing failure which, if not avoided, could
result in death or serious injury.
IMPORTANT:
Use only SAF-HOLLAND

Original Parts to
service the SAF-HOLLAND

P89 disc brake
axle.
